Right, so outfits-I'm not sure the rules surrounding this, but the wedding is at 2:00 so a simple dress will do, and for men a dress (hahaha just kidding), kackies, a button up shirt will do. To give you insight Adrian is wearing a suit not a tux, so this def is not a super dressy wedding. So no ballroom gowns or crazy sparkles (don't show me up because my dress is not the standard big poofy wedding dress).
Well I hope that helps. Let me know if you have any other questions!
